I've just got off the phone with TK. I didn't get very far. I asked three times for the customer service representative to update my reservation with my passport details. I explained twice that I couldn't do this online and that I wanted to enter my APIS details (I explained APIS and why it was required).

The CS rep said that as long as my date of birth was in the reservation then I was 'good to go' and 'nothing else is required'. He did confirm my date of birth.

I couldn't get him to budge on entering any other data even though I emphasised that the information was required for entry into the USA. I did a dummy booking yesterday on the TK website. It didn't ask for my passport details at any point before I got to the payment page. I'm quite certain that TK don't have this information.

I'll just have to sort it out at the airport.
